Application filed April 12, 1906. Serial No. 311.287.

To tlf/whom. it may colwcrnj Be it known that I, HENRY T. liiis'riari c and c', extending in two continuous lines,

citizeirof the United States, residing in Phil adelphia, Pennsylvania, have invented certain Improvements in Multiple-Circuit Panels, ci which the following is a specification.

' My invention consists in certain improvements in that class of electrical fixtures particularly designed to provide means for connecting and su porting electrical conductors and, if desiredl? fuseplug sockets at the points where feeders havino' two or more conductors divide into a xnuniber of vbranch circuits each having the same number of conductors.

One object ci my invention is to provide a distributing-panel of the above-noted ty e, which while consistingr of any desired num er I of sections shall occupy less space than has hitherto been consideredlpossible in similar x constructions lof kthe vsame capacity and which shall at the same time have its parts, arranged in such manner as will best vtend toward safet in o eration and economy of material. T eseo `jects I attain as hereinafter set forth, reference being had to the accompanying drawings, in which Figures 1 and 2 are respectively top and bottom plans ofone form of my invention,

the panel therein illustrated being particularly designed for usel on a two-wire circuit. Fi 3 is a side elevation oi' the panel shown in igs. 1 and 2.v` Figs. 4 and 5 are vertical sections taken on the lines e 4 and 5 5, re' spectively, of Fig. 1. Figs. 6 and 7 are respectively top and bottomplans'of a form of multiple-circuit panel pa rti-f"'ularlyv designed for use on a three-.wire circuit. Figs. v8 and9 are4 lans of multipleecircuit panels, showing ino iications of my invention and respectively designed for use on two and/three wire 'circuitsj and Figs. 10 and ll are inverted or bottomplans of the structures shown in Figs; 8 and 9, respectively.

Referring to Figs. l 130.5, inclusive, of the 'above drawings, A and A are bodies of insuloting material, such as porcelain, and upon the u per face of the iirst of these is carried I'. a dou le-pole switc'hB, whose blades are designed to connect the terminals b and b for .the attachment of supply-feeders to other4 terminals b2 and b3, respectively, all four oi these terminals being held in position on the insulating-block A .by screws, as shown in Figs. 2, and 4, which extend through the same. Bethel' the blocks A and A are provided with relatively deep elongated recesses and also have connecting with them branch recesses ci and c", respectively, extendingr substantiallyr at right angles to and between the saine in the under sides of said insulaty jacent side of the panel, and in each circular recess are fixed metallic terminals d and 'd' for cngagementlwith a fuse or cut-out plug, the first of said terminals consisting of a screw'or bolt having in the .present instance a hexagonal head and extending through to thebottom or under side ofthe block. The second terminal consists of the well-known threaded metallic ring or sleeve, and to this is electricallyconnected a laterally-extended' metallic piece d3, which ineach case extends into the straight recess connected to the corresponding fuse-plug recess. Each piece d has at its up er end a pair of lugs di, bent up- `wardly and aving midway between them a screw d5, with a washer, for the attachment of a branch electrical conductor.

On reference to Fig. 2 it will be seen that the recesses formed in the under surface of the two blocksI A and A are in two independ` ent sets, and in vthese are placed metallic strips e, e', f, and f of which the first two extend iii the branch and main recesses c and c2, respectively, while the last two extend in the branch and main recesses c and c3, fe-

spectively. I The screws d, forming one of the terminals of each of the fuse-plug sockets, extend into the various recesses in the under side of the blocks and form electrical connection with, as well as connect together, the various strips engaged by them.`

IOO

. One each of the strips e andf extends in the recesses c and c', formed partly in the block A and partly 'n the block A, so that they serve to rigidly connect or hold together said blocks, it being-noted that one of the strips the reception of a screw d, so that the expansion and contraction oi the material oi the blocks and strips is permitted without danger of cracking' or breaking the former.

`lll/ith the above arrangement of parts the has an elongated holo in one of its ends for y of four other fuse-plug sockets.

terminal b is connected through one of the blades of switch B tothe terminal b2 and thence through the st ripsfandj" to thecenter terminals d of four fuse-plugc sockets, while the. second terminal b is similarly connected through its switch-blade and the strips c and e to the center terminals ln each case the threaded sleeves of the fuse-plugr sockets are connected to the branch terminal pieces d, .Moreover, the arrangement of parts is suc-h that said terminal pieces d along each side of the panel are alternately of diil'erent polarity, so that anyvpair of feeders for a given branch circuit come off from the panel adjacent to each other. v

lt is of course evident that any desired additional number of blocks A', with their `sockets and connections, may be added in continuation of the `two blocks illustrated;

but since these are mere duplications of said blockA with similar recesses and parts, I have illustrated the main block A with but a single auxiliary.-

After the parts of the panel have been assembled fused insulating material is poured into the recesses c and c in the underside 0f said panel, so as to fill them Hush with'the bottom surface thereof, and in order to prevent escape of this material from the open ends of the two channels in the last `block-A', I form these, as shown in Figs. 2, 4, 10, and 11, with transverse sockets c5, extending into the sides and bottom parts thereof for'the reception of Such pieces w en in place extend across the ends of the recesses c and c and are oa height sufficient to prevent escape of the 'insulating compound, which hardens upon coolmg. It will be seen that with the arrangement of parts described and illustrated the fuseplug' sockets are ste gered relatively to each other, and thus ma e it possible to pince a given n'nmber of sockets 'on n blc-ek or bloc-ksof less over-all vdimensions than would other- Wise be the ense. Again, it will be seen'that by lacing;` the main connecting-bars e :mdf Witli their branches in recesses formed in the under sides of the insulating.- blocks the number of exposed conductors is reduced-to n. minimum, since when the various 'fuseplilgs are in place in their vsockets only titl switch-blades with their terininalsamithe various branch terminals nreiexposed. 'loI prevent possible short circuits' between-the with them an u'pwardlgprojecting arc shieldc", preferabl formed, as in the resent-itu stanceyintgral with the bod oft e ,block A.4

In Figs. 5 and 7 I have s lown my invention ns ndaptedfor use in connection with a imultiple-circuit pimel nn a. three-wire system, the switch inv this instance having three blades and the insulating-blocks A2 and AF terminal b3 ieces, usually of cardboard.

fuse-plug sockets of the pen'el. orinner conductor is connected throigh a blade of switch B to the neutral wire ol the 'circuitl and with the arrangement of insclugs illustrated the two terniinnls oi' each liranch circuit are connected to the multiplecircuit panel in' pairs, whileA the inse-plug sockets each have, as previously described, e. terminal for the connection of a ieedwire and are errang-ed in pairs along the sides of 'seid p'ancl. As before, it will be noted that 'the inseplug sockets nre staggered relatively to esci other, so as tn economico space.

'l'his center 'a relatively small panel i'or the :ncommodlfttion of n given number of sockets and branch circuits.

Other applications of my inx-'ention are shown in Figs. 8 tol l, inclusive, the arrangement being-sich that the switches are 'ninced ori-"the branelreirf'uit sides oi the inse-pings instead of on the feeder: sides, ns' in theI construction shown in Figs. i to 'i, inclut-ive. in al V case, however, the bars or strips serve to hold together the vnrious scctlnne or bocks constituting the. varioxis parts ol' the princi und are carried inclmnnels'or recesses formed independently oi' each other in the undersur face of said blocks, while the fuse wing socketsv are stne'terei'l reintively to each other in order not only to reduce the amount of ma- 't'erinl required, but nien to lessen the over-ali d imcnsions oiV the panel.
